You are correct about 9V batteries. A 10A short is about 90 Watts. But
have you seen the specs on a LiPo Battery?
I have a 18 volt nominal 8,000 mAH LiPo battery that is rated "40C". This
battery is safe and within design limits to discharge at 40 x 8,000 mA.
Yes, taking 320 amps out of the battery is acceptable, the battery is
designed for that.
The battery can continuously supply 5.7 Kilowatts over 2 times more power
then can a standard AC mains wall outlet. Of course at that rate it runs
out of power in roughly one minute. But you can do a LOT in one minute.
When you short the leads you get a LOT more than 320 amps
A battery like that costs only about $50 today so they are available to
almost anyone who wants one.
